Law enforcement officials reported finding evidence of motorcycle gang membership during a Wednesday search of the residence of an Arcata man suspected of drugging and kidnapping a McKinleyville woman.

At about 10 a.m. Wednesday, Humboldt County Sheriff's Office deputies, assisted by Arcata police and Humboldt State University police, served a Humboldt County Superior Court search warrant at 63-year-old Eric Eugene Lundin's home on the 1100 block of G Street in Arcata, according to a sheriff's office press release.

Deputies searching the residence found a .22 caliber rifle and large quantities of ammunition that matched the weapons seized from Lundin on Tuesday when they searched the house, the release said.

Deputies also reported finding evidence described in the release as items supporting Lundin's membership in the Mongols motorcycle gang, as well as additional evidence supporting the victim's statement to deputies.

The sheriff's office declined to further specify what evidence had been found, stating it was part of an ongoing investigation.

Additional weapons charges will be sought against Lundin, according to the release.

At about 11:55 p.m. Monday, the sheriff's office was notified of a possible kidnap victim being treated at a hospital emergency room, according to a previous sheriff's office press release.

Lt. Steve Knight said Wednesday he didn't know the extent of the woman's injuries, and for safety reasons, couldn't name the hospital.

The 63-year-old woman told a deputy that she was home alone at about 8 p.m. when she opened her front door.

Lundin reportedly grabbed the woman by the neck, pushed his way into the home, removed two semi-automatic handguns from his pockets, set them on the coffee table in front of the woman and ordered her to take three pills he said were methadone, according to the previous release.

Deputies found at least one bottle of methadone in the residence when they searched the home, Knight said. He also said he believes Lundin and the victim knew each other but doesn't know how. Any relationship is still being investigated.

After the woman took the pills, Lundin then allegedly ordered the woman into his pickup truck, driving her from McKinleyville to Arcata while telling her all the places he could hide her body, the previous release said. He eventually dropped the woman off at her home and told her he only wanted to scare her.

Lundin was arrested Tuesday on suspicion of kidnapping, assault, brandishing a firearm, burglary, being a convicted felon in possession of firearms, administering drugs to commit a felony, vandalism and transportation and possession of a controlled substance.

Deputies also recovered two loaded semi-automatic handguns. Lundin was booked into the Humboldt County jail. His bail was set at $100,000. Lundin was still in jail as of 6 p.m. Wednesday.

The sheriff's office is asking anyone with information about this case or related criminal activity to call the sheriff's office at 445-7251 or the sheriff's office crime tip line at 268-2539.
